A subarachnoid hemorrhage bleeds into the space between your brain and the surrounding membrane (subarachnoid space). The main symptom is a sudden, severe headache. The headache is sometimes associated with nausea, vomiting, and a brief loss of consciousness. Subarachnoid hemorrhage treatment in hyderabad
The bleeding usually results from the breakage of an abnormal bulge in a blood vessel (aneurysm) in your brain. Sometimes the bleeding is caused by trauma, abnormal entanglement of blood vessels in your brain (arteriovenous malformation), or other blood vessels, or health problems.

. The primary symptom is a sudden, severe headache. The headache is sometimes associated with nausea, vomiting and a brief loss of consciousness.
Bleeding usually results from the rupture of an abnormal bulge in a blood vessel (aneurysm) in your brain. Sometimes bleeding is caused by trauma, an abnormal tangle of blood vessels in your brain (arteriovenous malformation), or other blood vessel or health problems.
To diagnose a subarachnoid hemorrhage, your doctor is likely to recommend:
- CT scan. This imaging test can detect bleeding in your brain.Your doctor may inject a contrast dye to view your blood vessels in greater detail (CT angiogram).
- MRI. This imaging test also can detect bleeding in your brain. Your doctor might inject a dye into a blood vessel to view the arteries and veins in greater detail (MR angiogram) and to highlight blood flow.
- Cerebral angiography. You doctor inserts a long, thin tube (catheter) into an artery in your leg and threads it to your brain. Dye is injected into the blood vessels of your brain to make them visible under X-ray imaging. Your doctor might recommend cerebral angiography to obtain more-detailed images or if a subarachnoid hemorrhage is suspected but the cause isn’t clear or doesn’t appear on other imaging.
Treatment initially focuses on stabilizing your condition.
If your bleeding is caused by a ruptured brain aneurysm, your doctor might recommend:
- Surgery. The surgeon makes an incision in your scalp and locates the brain aneurysm. A metal clip is placed across the aneurysm’s neck to stop the blood flow to it.
- Endovascular embolization. The surgeon inserts a catheter into an artery in your groin and threads it to your brain. Detachable platinum coils are guided through the catheter and placed in the aneurysm. The coils fill the aneurysm, reducing blood flow into the aneurysm sac and causing the blood to clot.
- Other endovascular treatments. Certain aneurysms can be treated with endovascular embolization that uses newer technology such as stent-assisted or balloon-assisted coiling or devices that divert blood flow.
